Slingshot is claimed to be capable of turning any water source such as urine or saltwater into drinking water. Dean Kamen invented the Slingshot. Kamen filed U.S. patent # 7,340,879 on November 13, 2003 for the device which was issued on March 11, 2008. 2005 YouTube Born from the PayPal Mafia in 2005, YouTube is the world's most popular video sharing site. In 2006, Google bought YouTube for $1.65 billion. 2006 Blu-ray Disc A digital optical disc data storage format. It was designed to supersede the DVD format, and is capable of storing several hours of video in high-definition. 2007 Nanowire battery A nanowire battery is a lithium-ion battery consisting of a stainless steel anode covered in silicon nanowires. Silicon, which stores ten times more lithium than graphite, allows a far greater energy density on a steel anode, thus reducing the mass of the battery. The high surface area further allows for fast charging and discharging. The practicality of nanowire batteries is reasoned that a laptop computer that runs on a regular lithium-ion battery for two hours could potentially operate up to 20 hours using a nanowire battery without recharging, which would be a considerable advantage for many people resulting in energy conservation and cost savings. The nanowire battery was co-invented in 2007 by Chinese-American Dr. Yi Cui, an assistant professor of materials science and engineering along with his colleagues at Stanford University. 2007 iPhone The iPhone is a line of smartphones designed and marketed by Apple Inc. All generations of the iPhone use Apple's iOS mobile operating system software. The first-generation iPhone was released on June 29, 2007, and multiple new hardware iterations with new iOS releases have been released since. 2007 Amazon Kindle In 2007, Amazon released the original Amazon Kindle e-book reader. While not the first of its kind, the Kindle led the charge to popularizing e-books and e-readers. 2008 Bionic contact lens A bionic contact lens is a digital contact lens worn directly on the human eye which in the future, scientists believe could one day serve as a useful virtual platform for activities such as surfing the World Wide Web, superimposing images on real-world objects, playing video games for entertainment, and for monitoring patients' medical conditions. The bionic contact lens is a form of nanotechnology and microfabrication constructed of light emitting diodes, an antenna, and electronic circuit wiring. The bionic contact lens is the 2008
